I see, you are impressed from some mythology about 'bad commies'. You should better read some classic memoirs (Russian or German) about the issue before go for conclusion.
However, I understand, there is stiffness of control about publication in Internet in US, effectively prevents for best publication to be published for free. so I have reverse-translated for you (from Russian) some good parts from the famous Germany tank officer Carrius memoirs. He narrates about his first meet with T-34:
"....The deaf rumble, which was being moved from the northeast, woke us once in the morning. We several minutes strained rumor, after which already nothing could hold us in the buried shelters. Outside snow-storm with the prickly snow intercepted respiration . For the Russians this was ideal weather for the attack. Without expecting alarm signal, we woke company. Our suspicions were confirmed. Report soon entered, that the Russians burst open. We found the commander of luftwaffe field division in the control center in the state of complete desperation. He did not know, where its subdivisions were located.
Russian tanks rumpled everything all around before the anti-tank guns had produced even a shot. Ivans took all our weapons we received before, and division scattered in different directions. Fortunately, the enemy after rapid initial victory immediately stopped. He feared to fall into the ambush. With some efforts our regiment could close the breach. This was really mad house!"
and further:
"One additional event struck on us as the ton of the bricks: for the first time appeared Russian tanks "T -34"! The astonishment was complete. How it could happen out there, while the top commanders did not know about existence of this excellent tank? "T -34" did grow prettier by armor, by ideal form and by splendid 76, 2- mm long-barrelled MG, bring everybody into the trembling, and all German tanks up to the end of the war was scared it. What we can do with these monsters, which were throw against us? At that time 37- mm the gun was still our strongest anti-tank weapon. Being lucky, we could hit the bottom of tower "T -34" and wedge it. For even more greatly luck, tank after this will not be able to act in combat effectively. Certainly, it's not very encouraging situation! Only resolve in such situation was 88- mm the anti-aircraft gun."
